El Salvador's Court of Accounts, which oversees its public resources, will investigate a complaint about the government's Bitcoin purchases and the construction of kiosks for cryptocurrency ATMs, according to a document seen by Reuters on Friday. El Salvador became the first country in the world to adopt Bitcoin as legal tender this month, a move championed by the country's popular President Nayib Bukele. The government has also launched a digital wallet, Chivo, which is linked to newly-built cryptocurrency cash machines that allow users to withdraw physical money from their digital bitcoin holdings. Its roll out has been plagued by glitches.

To really understand what is special about Bitcoin, we need to understand how it works at a technical level. How does Bitcoin work?
What makes Bitcoin different? How secure are your Bitcoins? How anonymous are Bitcoin users? What determines the price of Bitcoins? Can cryptocurrencies be regulated? What might the future hold? It does not offer a certificate upon completion. It is one of the eight universities of the Ivy League, and one of the nine Colonial Colleges founded before the American Revolution. Learn about cryptographic building blocks "primitives" and reason about their security.
Work through how these primitives can be used to construct simple cryptocurrencies. Learn Bitcoin's consensus mechanism and reason about its security. Appreciate how security comes from a combination of technical methods and clever incentive engineering. Learn how the individual components of the Bitcoin protocol make the whole system tick: transactions, script, blocks, and the peer-to-peer network. This week we'll explore how using Bitcoins works in practice: different ways of storing Bitcoin keys, security measures, and various types of services that allow you to trade and transact with bitcoins.
We already know that Bitcoin relies crucially on mining. But who are the miners? How did they get into this? How do they operate? What's the business model like for miners? What impact do they have on the environment?
Is Bitcoin anonymous? What does that statement even mean—can we define it rigorously? We'll learn about the various ways to improve Bitcoin's anonymity and privacy and learn about Bitcoin's role in Silk Road and other hidden marketplaces. We'll look at all the ways that the world of Bitcoin and cryptocurrency technology touches the world of people.
We'll discuss the community, politics within Bitcoin and the way that Bitcoin interacts with politics, and law enforcement and regulation issues. Not everyone is happy about how Bitcoin mining works: its energy consumption and the fact that it requires specialized hardware are major sticking points.
This week we'll look at how mining can be re-designed in alternative cryptocurrencies. One of the most exciting things about Bitcoin technology is its potential to support applications other than currency. We'll study several of these and study the properties of Bitcoin that makes this possible. Hundreds of altcoins, or alternative cryptocurrencies, have been started, either to fix Bitcoin's perceived flaws or to pursue different goals and properties.
We'll look at everything that goes into an altcoin and how they interact with Bitcoin. The use of Bitcoin technology for decentralizing property, markets, and so on has been hailed as a recipe for economic and political disruption. We'll look at the technological underpinnings of these proposals and the potential impact on society.
I've gained a strong knowledge of Bitcoin's architecture but wish this course was updated to include the developments of the last two years. A few lectures on alt-coins would have been useful as well. Great course, a very broad and in-depth overview of concepts surrounding cryptocurrencies and Bitcoin in particular.
Would be great to have an update of course; perhaps once the ICO craze is over? I find this course prepared very well. There are many perspectives and this course does not concentrate on the technology only. I find this course very helpful. The level is more then just beginner. I enjoyed the lecture series. As many have stated previously, I do think that the assignments assume a sizeable amount of technological knowledge that is not necessarily cohesive with the lectures. Access to lectures and assignments depends on your type of enrollment.

Select any ticker for detailed metrics. Click the copy icon in the upper right corner of card to copy and share. The Sharpe ratio is a measure of risk-adjusted really volatility-adjusted returns. It is a way to measure how much return an investment generated for the risk volatility endured over some time horizon. The Sortino ratio is the excess return over the risk-free rate divided by the downside semi-variance, and so it measures the return to "bad" volatility. It is a variation of the Sharpe ratio, differentiates harmful volatility from volatility in general by using a value for downside deviation.

CISAC has four technical committees that provide expert, specialised guidance on the administration of royalties for creators. The BTC is a committee responsible for creating, implementing and troubleshooting all standards and procedures related to documentation and revenue distribution across all fields of creativity. The MTC is a committee responsible for addressing issues related to both online and offline licensing, including mechanical and performance rights. The MTC aims at dealing effectively with all licensing topics through cooperation with the DLV and AGP committees, and ensuring the representation of under-represented repertoires. The MTC also enables collateral projects related to documentation and distribution issues, such as multi-territorial licences. The main task of the DLV is to facilitate sharing information on all matters relating to rights administration in DLV works and to develop common tools for documentation, licensing and distribution, for example. It encourages and organizes cooperation and collaboration between CISAC members on all matters related to the promotion and administration of rights.
